Chainsafe Gaming web3.unity 在没有元掩码交互的情况下调用函数

Question

我正在统一制作一个 WebGL 游戏，两个玩家可以在其中进行比赛。在游戏结束时，获胜者由游戏决定。我的游戏将调用我的合约的 declareWinner 函数，您可以在下面看到它。

问题是它总是需要我手动与 metamask 交互并进行交易。我只想要一个自动化过程，其中游戏只调用 declareWinner 函数，它应该完成工作。请注意，我还有 JoinRoom 功能，它将创建一个新房间并保存每个房间的所有数据，包括中标价格。

我已经在 BSC 测试网上部署了我的智能合约，我正在使用 Chainsafe 游戏 web3.unity SDK https://docs.gaming.chainsafe.io/.

目前我使用的是最新版本的 Chainsafe 游戏 SDK(v2.1.0)。

pragma solidity ^0.8.19;

contract FPS {
    struct Room {
        address player1;
        address player2;
        bool isFull;
        uint256 winnings;
        bool ended;
        address winner;
    }
 function declareWinner(string memory roomId, address winner)
        external
        onlyOwner
    {
        Room storage room = rooms[roomId];
        require(room.isFull, "Room is not full");
        require(
            winner == room.player1 || winner == room.player2,
            "Winner must be one of the players of this room"
        );
        require(!room.ended, "This room has already ended");
        room.ended = true;
        room.winner = winner;
        uint256 winnerAmount = room.winnings;
        payable(winner).transfer(winnerAmount);
    }

}

因为我试过这个。这将打开 Metamask 以供手动进行交易。

public async void DeclareWinner()
    {
        string contractAbi = ContractDetails.ContractABI;
        string contractAddress = ContractDetails.ContractAddress;
        string method = "declareWinner";

        string roomId = RoomIDInput.text;
        string winner = Winner.text;
        string[] obj = { roomId, winner };

        string args = JsonConvert.SerializeObject(obj);

        string value = "0";
        string gasLimit = "200000";
        string gasPrice = "20000000000";
        try
        {
            string response = await Web3GL.SendContract(method, contractAbi, contractAddress, args, value, gasLimit, gasPrice);
            WinnerTxt.text=Winner.text;
        }
        catch (Exception e)
        {
            Debug.Log(e, this);
        }
    }
